im pretty new to react and have wrote an application, the application runs perfectly on the local server yet when i'm trying to build it for production i run into the above error, i cant find any reference to a Parser class, similar questions say that it's to do with an error with Babel trans-piling ES6 classes but i'm using the latest version of CRA and have followed the examples for creating Components on the docs.
The only exception I have to this is that i'm using React-Straps for a Modal component (the only component using this in my application). Can anyone advice on this error (as usually this error throws for hand written components)
EDIT: i tried to create a fresh app and this built successfully
